INITIALIZATION
The DRV2667 features a simple initialization procedure.
Initialization Procedure
1. Apply power to DRV2667 .
2. Wait for 1 millisecond before attempting an I
2
C write for the DRV2667 to power up.
3. Exit low-power standby mode by clearing the STANDBY bit (Register 2, Bit[6])
4. If using the digital interface mode, choose the desired timeout period (Register 2, Bit[3:2]).
5. Choose the interface mode, analog or digital (Register 1, Bit[2]), and gain setting (Register 1, Bit[1:0])
6. If using the digital interface mode, the device is now ready to receive data. If using the analog input mode,
set the EN_Override bit (Register 2, Bit[1]) to enable the boost and high-voltage amplifier and begin sourcing
the waveform to the analog inputs.
